The electrical engineers invented a plant that just needs a piece of land about the size of half a tennis court and sunny weather to toast up to 50kg of coffee an hour. No gas, no electricity, just sun rays concentrated by a set of mirrors on a rotating steel basket filled of fresh coffee grains. (AP Photo/Andrew Medichini)
